I found this artist who is really good with her drawings and colors, she does it in a computer, I love the dress that I saw. It's lovely! It's not a doubt about that. She has here done a impression of one of Dior's gowns... AnaLee is really talented. You'll see why if you scroll down.
I love them both, I'll let you just take in that you can do an impression so well and lovely.
This dress is a little bit to expensive to just do replicas in fabric off... It's Haute Couture.
Here's some blogs about lot of AnaLees work.
